The BARBARA project developed an injection-moulded PLA food jar containing a chlorophyll-derived green pigment and natural fibres from artichoke pruning waste. The demonstrator combines a bio-based polymer with recovered agricultural materials.
The chlorophyll-derived pigment provides colour, while the artichoke fibres act as reinforcement within the material. The jar demonstrates how bio-based colourants and agricultural sidestreams can be incorporated into food-packaging products.
